Battery Notice
To ensure that the battery maintains its maximum capacity,
operate the computer on battery power at least once a month
until the battery is fully discharged. Please see
for procedures. If the computer is
continuously operated on AC power, either through an AC
adapter or a docking station (if applicable to your system), for
an extended period (more than a month) the battery may fail
to retain a charge. This may shorten the life of the battery, and
the battery light may not indicate a low-battery condition.
In addition, the computer has an internal real-time clock
(RTC) battery. This is a nickel metal hydride (NiMH) battery.
The RTC battery powers the RTC memory, which stores your
system configuration settings and the current time and date
for up to a month while the computer is turned off.
Using additional batteries
If you spend a lot of time traveling and need to work for
many hours without an AC power source, you may want to
carry additional charged batteries with you. You can then
replace a discharged battery and continue working.
NOTE: For optimum DVD performance, Toshiba recommends that
you play DVDs while running on AC power rather than on battery
power.
